Autonics BWP20-12 Area Sensor
Autonics BWP20-12 Through-Beam Area Sensor (20 mm Pitch, NPN Output)
Autonics BWP20-12 is a high-resolution through-beam area sensor with 12 optical axes and 20 mm pitch, designed for accurate detection of small and closely spaced objects in industrial automation systems.
The Autonics BWP20-12 is a through-beam area sensor engineered for high-precision detection using a 20 mm optical axis pitch. With 12 optical beams, it provides an extended sensing height while maintaining high resolution, making it suitable for detecting small objects over a wider area.
Featuring NPN open-collector output, IP65 protection, and advanced self-diagnostic functions, the BWP20-12 delivers stable and reliable performance in demanding industrial environments.
